To all whom 'it may concern:

Be it known that we, THOMAS N DALE, Jr., and GEORGE KRAINK, of Paterson, in the countyof Passaic and State of -New Jersey,

in- Spinning, Doubling, and Twisting Machinery and we do hereby declare that the following is a full, clear, and exact description thereof, which kwill enable others skilled in the art to make and use the saine, reference being had' to the accompanying drawing, forming Our invention. relates to spinning and doubmachine, but is also applicable-t-o wool and other fibers. t .W e will'rst describe our invention in connection with allfthat is necessary to a full understanding thereof', and then clearly point it out in the claims. g I

Fig. 3 isa front elevation, and Fig. 4 is a sectional elevation, ofthe same when Similar letters of reference indicate corre-V The'organzineor warp is made of two threads of raw silk by iirst twisting them separately, then doubling them, andiinally twisting them together, the final twisting being done lin the and iirm.

. The tram or weft is made of threads of raw silk also, using two or more, which are first doubled and then twisted' to make -a soft and elastic thread more suitable for illing;V

vA is a suitable frame, of wood or metal, made considerably higher than the ordinary doubling or single row twisting-machines and aslong as may be required for the number of spindles or sets of spindles to beused.

B represents the spindles ouwliich the bobbins C, containing the silk, are placed, for spinning the separate threads and delivering them to the doubling apparatus and twisting "head I, over the iiiers being provided with suital'ile-k iiiers, and operp percrm the first twisting operation on the single threads for the warp as they-are drawn from the ,b ob-A bins C, The said threads are conducted over the guide-wires D, wire E, 'and fallers F to the-grooved "dioublingand drawing rollers G,

H, thence to and through the hollow twisting K, or one of them, and to the bobbin L, where it is wound in the iinished condition,the doubling being effected by the rollers Gr H, and the final twisting-hy the tubular twisting-head l and the iiiers K.-

By this simple means the several-operations are readily and economically performed; but the successful execution of them togctherlemands such an arrangement that in all cases the several threads to be united in one shall have exactly the same tension, .or as nearly so as possible; and herein', and for lack of means for stopping all the parts simultaneously vin case ofthe breaking of a thread., lies the didieulty which up to this time has prevented the performance of the said operations simultaneously and in one machine.

Ii'. the threads have not the saine tension,A or if one'thread be broken, the imperfection made in the surface of the woven goods by'tlrefthus weakened warp-thread breaking inthe loom is more marked in silk goods than any other, owing to. the high finish ofthe same, and these imperfections are more to be guardedagainst on account of the expensive character of the goods; hence the importance of making the most perfect threads. We have therefore provided an arrangement ot'driving mechanism'for gearing the spindles, twister, and'doubling and drawing rollers together, sot-hat all work ia the exa-ct relation to each other require-, and in ease a thread breaks all the moving partsi. c. the spindles,doublers, and

twisters-will be simultaneous-l y thrown out of gear. p

M represents the cylinder for driving the spindles B; N, the one for driving the twist- I ers I, and also the rollers Gr Il. Thesctwo eyll inders are, in practice, connected together by gear-wheels and a shaft, so as to be moved at Jthesame relative speed, and thespindlcs and 4twistcrs are driven from them by belts O Pin the ordinaryway. The belts 0 work in the grooves of the pulleys Q, having the reducedy onto which the belts are or coniealpperpart-s,

thrown by the Shifters R, one pair being used for each pair of spindles when they are to be thrown out, This saves power and bands when only-part of the spindles are to be used. I The Shifters R are connected 'to a vertical rod, S, which is 'worked by a lever, T, pivoted at,` U

.and connected to the drop-rod Y.-

.NV is abrake, designed to be brought up rATERsoN, NEW .Hanser pose the studpin ofthe wheel h is The 'belt P works through the'shifter Y on 4the fast pulley a of the twister I, and is thrown up onto the loose pulley by its shifter when the drop-rod V falls, the said shifter beingv connected to the said rod by the lever d, andk arm i The drawing and doubling' roller G is operated by a shaft (1. and wheel (l2 eeari'n with sha-ttf by a wheel, j", thereon;` This shaft fis driven by the c vlimlerNt-hrough suitable gearwheels, y h yi, which impart toit a positive moltion. These' whcels are, ofcourse, arranged to givethe-reqnisite speed to the drawing-rollers; but it is sometimes necessary to change 'their speed for different kin ds of work. This is done bychai'igin g the gear-wheels h fi, for which purarranged in as'lot to admit ot' ina-king the said changes. By such chan the twist of the warp or other 'thread being made may be varied.

The bearing of the shaft d next to the shaft f' is-constructed so as to allow the shaft to slide to disconnect the v gear-wheels L2 f', and the wheels are held *in gear by a bell-crank, k, pivoted at m, and resting at one enden a studpin proiecting from the drop-rod. The other end ofv the said crank-lever bears'against the- Vshaft d1 when the drop-rodv is raised, and holds it in lgear. y v -f u is a hand-lever, pivotcd at p, and arranged with the said drop-rod for raising it, when it is desired to set 4the several parts in gear, by

properly moving the'belt-shifters and the bellcrank 7:. It is held up by the stud q on the end of 4the short bent tripping-rod amounted inthestands s, -to be acted on by thc hollow tiltingllever t, pivoted at u, and arranged to bezthrown up at the rear end to turn the said tripping-rod and let the drop-rod fall by the dropping of the faller-wires I which, being heldnp-against the rodF' by the threads,

arel'et fall when they break on the front end. of the tiltingflever t, thereby stopping all the appara-tus at once by throwing oit" the belts, movin g the lever k away from the shaft d* to let its wheel slip out, and bringing the brakeNV up against the pulley Q on the spindles B. This hollow lever t is provided with one or more tilting-balls, which ,greatly assist in carrying the front end down as soon as tilted far enough by the fa-llers to incline it that way. i

We attach the tube I to the iiier K, making it the support and means of rotatingit, the driving-pulley being attached to it, and conduct the doubled thread up through the said hollow axis, and thence to the arm of the ilier, thereby twisting the threads Vin the said tube.

The bobbin L, which receives the twisted rails of the said rack.

thread, is suspended by the fixed spindle Ll on the bar L2, which is arranged to traverse upand down on the ways L3. The traverse motion Amay be produced by any suitable arrangement of means, which, not being part of our invention, is not shown,

The said Ybobbin L is provided with a frictionspring, L4, which may have 'a temperscrew or other suitable device for varying its pressureandthe friction thereof', according to the cond'tion of the bobbin, as when it is tirst put on, anbefore ithas received much thread, it would run too light'andfif'ast--,` which would make-'the' bobbins too soft?" Thelsaid-tem perscrew is to be adjuste'dfrom., timeto 'itiinebythe'attendant. 'f

lForrnaking the weft the threads of which are'not to be twisted previous to doubling, we place the bobbins containing the same in the rack 1,` whichis detachably connected to the front board 2 of the machine, so as toV be re-I 1noved when not required. In this case the bearings in the rack for the journals of the bobbins are formed by the slots 3 in the side We propose to arrange these vbearings as to depth so that the;T will support the bobbins 4 at equal distances fromthe rod E, over which the respective threads pass before golng to the doubler-rolls, so that exactly the same length of thread-from each bobbin will be under tension, thereby insuring the 'equality of the tension as much as possible.

friction-bar, 5, and weight (iYV to, produce the necessary tension.

Of course the spindles B are not used when doubling and twisting the weft; but these operations are in other respects the saine as those described for the warp, and need not, therefore, be repeated.
